What will it mean when there are other entities that (who) are intelligent on a human scale (e.g. master of technology, complex planning, and long-term planning?) This is a question that science fiction has addressed many times and in many ways. Tchaikovsky’s approach is interesting because it doesn’t just ask what if one produced a computer intelligence or if another biological species became (human-style) intelligent, but – instead – it imagines an entity that combines human and animal intelligence with computer capabilities and protocols?
The protagonist, Rex, is a supersized dog-man optimized and super-powered for warfighting. Rex’s general intelligence is about at an elementary school level, but his instincts, programming, and capacity to process and analyze complex and abundant information make him much more competent than that level of intelligence would suggest. The dog-part of Rex has the simple animal instincts that make dogs both loving pets and devastating predators, with both capacities rolled into one (even if one side often remains latent.) His human capacities include a limited ability to reason and – crucially – the ability to communicate via language. The computer part of Rex, besides giving him the ability to process and respond to multiple information streams at once effectively, keeps him in check by creating a hierarchy of command and by giving feedback by way of a crude proto-emotional system (i.e. feelings of being a “good dog” or “bad dog.”)
Rex is the leader of a squad of creatures of various speciation. There is a giant bear named Honey, who serves as the team’s heavy weapons platform. She’s easy to see but packs a wallop in weapons and strength. There is a reptilian member called “Dragon” that genetically shares certain lizard characteristics. Dragon is a sniper. He is stealthy, and exists to take out particularly designated targets. Staying hidden is essential because Dragon doesn’t have the fantastic durability of Rex or Honey. The final team member is Bees, a swarm intelligence of bees. Bees can go anywhere by flight, can disperse or gather as needed, and can sting with various styles of poison. The individual bees of Bees are fragile. However, losing a few here and there has little effect on Bees capacity, but its intelligence does degrade with continued loses, and the ability to act and think as a unit disappears altogether at some level of loss.
The antagonist throughout most of the book is a man named Murray, who is an overzealous military contractor carrying out a brutal war in Central America using teams like Rex’s, but also laying waste to the Geneva and Chemical Weapons Conventions as he sees fit. (The book imagines a world in which the United Nations and global corporations are strong, but national governments are weak – at least relatively.) To cover up his war crimes, Murray kills a technician named Hartnell who is beloved by Rex (though below Murray – his “Master” – in Rex’s hierarchy,) but not before Hartnell can jettison Rex’s command hierarchy. This puts Rex in a rudderless position of having to make his own decisions. While the hierarchy is gone, Rex still has canine instincts and gets signals from his feedback chip. He doesn’t have to follow orders, though it’s still his inclination to do so. Two classes of individuals sit easy with Rex. Friends are individuals that one protects at any cost. Enemies are individuals that one destroys at any cost. Rex has sufficient intelligence to recognize that not everyone fits smoothly into one of these classes, but he doesn’t know how to respond to such individuals.
After Rex and team go “off-leash,” he is adrift in a world he doesn’t quite understand and there are events going on behind the scenes that he can’t fathom. Left entirely to his own devices, Rex might yield to his instinct to try to return to his Master (Murray) and try to get back to life as usual. However, while in command, Rex has gotten used to taking the advice of Honey because he realizes that she is more intelligent than he. (What he doesn’t recognize is that Honey was accidentally over-engineered and is super-intelligent – i.e. smarter than the smartest humans. She is quietly using that intelligence in the background, including finding allies.) While Rex is an autonomous decision maker, he isn’t at ease with this autonomy, and finds himself processing conflicting arguments to make challenging moral decisions throughout the book. Using the combination of his canine instinct to protect friends and fight enemies and his (albeit limited) human capacity to draw conclusions based on information, Rex tends to make satisfying decisions. Though the author does show Rex making cringe-worthy decisions as well. This way the reader feels the stakes, and recognizes that Rex’s mish-mash of instinct, thought, and programming could lead to a poor moral choice at any moment. (If this internal conflict seems complicated, it’s not so much different from the potential wars between the reptilian, mammalian, and human [prefrontal cortex] brains that we see in human beings.)
I enjoyed this book tremendously. I found it hard to put down. It does have intense scenes of violence, but that raises the stakes. Because, the book also asks an interesting question about what “someone” like Rex would be considered and what the legal and moral response to it would be. Is Rex a person, with all the the rights and responsibilities of that condition? Is he an animal that faces the same logic we apply to dogs (i.e. no animal cruelty allowed, but dogs that bite must be put down?) Or is he something else, and what does that mean? Can Rex be decommissioned like a bomb or a tank? What is the legal and moral obligation to an intelligent creature that can be [but isn’t necessarily] a killing machine? Is it right to create an intelligent entity and then install a command hierarchy such that it is a slave to the wishes of others?
If you enjoy science fiction, I believe you’ll find this book intense and entertaining.
